As the network design and standards authority for NSW Transport Assets, as specified in the ASA Charter, the ASA identifies, selects, develops, publishes, maintains and controls a suite of requirements documents on behalf of TfNSW, the asset owner. The ASA deploys TfNSW requirements for asset and safety assurance by creating and managing TfNSW's governance models, documents and processes. To achieve this, the ASA focuses on four primary tasks: • publishing and managing TfNSW's process and requirements documents including TfNSW plans, standards, manuals and guides • deploying TfNSW's Authorised Engineering Organisation (AEO) framework • continuously improving TfNSW’s Asset Management Framework • collaborating with the Transport cluster and industry through open engagement The AEO framework authorises engineering organisations to supply and provide asset related products and services to TfNSW. It works to assure the safety, quality and fitness for purpose of those products and services over the asset's whole-of-life. AEOs are expected to demonstrate how they have applied the requirements of ASA documents, including TfNSW plans, standards and guides, when delivering assets and related services for TfNSW. Compliance with ASA requirements by itself is not sufficient to ensure satisfactory outcomes for NSW Transport Assets. The ASA expects that professional judgement be used by competent personnel when using ASA requirements to produce those outcomes. About this document This is a signals and control systems standard for the heavy rail transport mode. It defines the interface requirements between rolling stock and the signals and control systems. This is a second issue and includes the following changes: • update to the automatic train protection (ATP) to cover the revised ETCS Level 1 LS implementation • details a rolling stock authorisation process for Authorised Engineering Organisations (AEOs) to test and approve rolling stock • enhancement of the guidance notes for the testing of rolling stock • inclusion of interface requirements for axle counters © State of NSW through Transport for NSW 2017 Page 4 of 71 T HR SC 00006 ST Rolling Stock Signalling Interface Requirements Version 2.0 Issued date: 07 July 2017 • provision of track circuit actuator requirements • inclusion of a reference to electrical specification T HR EL 08002 ST Relative Positions of Signals and Open Overlaps © State of NSW through Transport for NSW 2017 Page 5 of 71 T HR SC 00006 ST Rolling Stock Signalling Interface Requirements Version 2.0 Issued date: 07 July 2017 Table of contents 1.
